All that the experiments demonstrate is that the wave function evolves unitarily between state preparation and measurement. This is most easily accounted for by assuming that the wave function is a purely epistemic vehicle for the time evolution of probabilities. Since it is purely epistemic, collapse is not a problem since it is not a physical event. One does not have to go the whole way to QBism -- the wave function can still be objective (inter-subjectively agreed).
